Material meter cleaning device of dumper, dumper system and unloading method thereof

Abstract

The invention relates to the field of car dumpers and discloses a materialplanner cleaning device of a car dumper, a car dumper system and an unloading method of the car dumper system. The materialplanner cleaning device comprises a cleaning module (1) for cleaning a materialplanner, a control module for controlling the cleaning module (1), and a measuring module electrically connected with the control module and used for measuring the overturning angle of a carriage dumping materials into a hopper of the car dumper. The control module is arranged to control the cleaning module (1) to clean the materialplanner after receiving the information, fed back by the measuring module, of overturning of the carriage from the horizontal position to a first preset angle, and thus the cleaning module can clean the materialplanner within the time quantum when the carriage is overturned to enable a material flow to shield a detection route of a measuring device or to enable material flying dust to affect the measuring result of the measuring device. The car dumper operates circularly, the cleaning device can conduct cleaning operation circularly correspondingly, measurement of the materialplannercannot be affected, and meanwhile the accuracy and stability of the measuring result of the materialplanner are ensured.

Description

technical field [0001] The invention relates to the field of dumpers, in particular to a material meter cleaning device for a dumper, a dumper system and a material unloading method for the dumper system. Background technique [0002] At present, the hopper material level monitoring devices of the coal wharf dumper system mainly include inclined material level mercury switches, radio frequency admittance material level switches and radar material level monitors. Among them, the inclined material level mercury switch and the radio frequency admittance material level switch are generally installed inside the hopper of the dumper. During the coal dumping process, affected by factors such as the impact of the material flow and the vibration of the dumper, the frequency of damage is relatively high, and both The switch value can only monitor a certain point inside the funnel, so there is a monitoring blind spot, and there are potential safety hazards in the application. The rada...
